Since Bob doesn’t earn any money and lives off the taxpayer’s hard work, preferring to let the government steal money that doesn’t belong to them or him, I doubt he’s paid income tax in many years.
It’s wrong to call these donations to a “nonprofit organization,” as it implies they are a legally authorized charity and that donations are subject to the governance actual non-profits must comply with. It also suggests the suckers donors will get a tax deduction.
Bob can’t ever bring himself to tell the truth, and the truth is that these are not donations to a nonprofit organization. They are unwisely given gifts to a man unwilling to work for his luxuries in life or for his basic essentials.
TL;DR: If Bob was a Christian, he’d tell the truth instead of deliberately lying to rip people off.
